Latest Patents

Dreyfus's latest patents highlight groundbreaking techniques for integrated circuit testing. One of his notable inventions is the **full chip integrated circuit tester**, which utilizes contactless probing through pulsed ultraviolet laser light. This innovative process generates photoelectron emission depending on the potentials at micropoints on an integrated circuit. The emitted two-dimensional electron pattern is then converted into a luminescence pattern, which can be reviewed through video/computer scanning. The contactless oscilloscope he developed allows for simultaneous monitoring of logic states and switching waveforms across a full array of micropoints while offering flexibility by functioning in both vacuum and air environments.

Another significant invention is the **photon-assisted tunneling testing of passivated integrated circuits**. This technique involves applying a thin conductive overlayer to cover metal test pads on a passivated integrated circuit, enabling access to these pads via pulsed laser for voltage-modulated testing. This method allows for nondestructive testing and facilitates the examination of integrated circuits without the need for mechanical probing, ensuring that the passivation layer is preserved while still lowering the threshold for photoelectron emission.
